Camp Pitcher, with its many pleasant and some unpleasant associations, was abandoned on March 4th, when we moved about four miles and laid out a new camp about a mile from the Potomac creek bridge. On the same day our regiment was reassigned to the First Brigade, commanded by Colonel Collis, who was succeeded a few days afterward by Gen. Charles K. Graham. The brigade consisted of the following named Pennsylvania regiments: 57th, Colonel Sides; 63d, Colonel Kirkwood; 68th, Colonel Tippen; 105th, Colonel McKnight; 114th, Colonel Collis; and 141st, Colonel Madill. Lieut-Colonel Sides, formerly captain of Company A, of the 57th, returned to the regiment on the field at Fredericksburg, and took command after Colonel Campbell was wounded. The latter had been promoted brigadier general, and when able for duty was assigned to the Army of the Northwest, where the Indians of Minnesota and Dakota were on the warpath and committing great depredations. Campbell had wished to be assigned to a command in the Army of the Potomac, and did not like to be sent West. About this time a friend of writer, J. T. Chase, of Titusville, Pa., met Campbell in Harrisburg, and reported him as saying: "The rebels tried their damnedest to kill me at Fair Oaks and Fredericksburg, and now I'm to be sent out West to be scalped by the Indians." The 57th were much attached to Campbell and nothing would have pleased them more than to serve in a brigade commanded by him. As spring advanced we were kept busy with camp duties. Among these were the frequent inspections, by companies, regiment, or brigade. Guard mounting was by brigade, with great ceremony, which was always witnessed by many officers and men who were not on duty. It was General Hooker who introduced the system of corps badges into the army. The badge of each corps was of a different design and were of different color in the several divisions of a corps, being red for the first division, white for the second, and blue for the third. The designs of the different corps badges were: 1st corps, a sphere; 2d, a trefoil; 3d, a diamond; 5th, a Maltese cross; 6th, a Greek cross; 11th, a crescent; and 12th, a star. The badge was made of cloth and was sewed on the top of the cap. By this arrangement, one could tell at a glance to what corps and division a man belonged, and it was of much importance in preventing straggling on the march, or skulking in battle. The badge system was eventually adopted by all other armies in the field. The 57th belonged to the first division of the 3d corps, wore a red diamond, and are proud to wear it today at all old soldiers' gatherings.
